Adhering glass cover sheet to a frame

Abstract

Disclosed herein are embodiments of a method of forming a glass article having a glass cover sheet and a frame. The glass cover sheet includes a first major surface and a second major surface in which the second major surface is opposite the first major surface. The frame has a support surface. In the method, a pressure-sensitive adhesive tape is applied to a first region of the glass cover sheet or of the frame. A liquid adhesive is applied to a second region of the glass cover sheet or of the frame. Pressure is applied to the glass cover sheet and the frame to cause the pressure-sensitive adhesive to adhere the glass cover sheet to the frame at a first bond strength. The liquid adhesive is cured to adhere the glass cover sheet to the frame at a second bond strength that is greater than the first bond strength.

What is claimed is: 
     
       1. A glass article, comprising:
 a glass cover sheet having a first major surface and a second major surface, the second major surface comprising at least a first curve; 
 a frame having a support surface comprising at least a first complementary curve, wherein the second major surface of the cover glass sheet faces the support surface of the frame and wherein the first complementary curve is complementary to the first curve; 
 a pressure-sensitive adhesive tape disposed in at least a first region between the support surface of the frame and the second major surface of the glass cover sheet; and 
 a cured liquid adhesive disposed in at least a second region between the support surface of the frame and the second major surface of the glass cover sheet, wherein the pressure-sensitive adhesive tape and the cured liquid adhesive retain the glass cover sheet in a cold-formed state such that that the first major surface and the second major surface comprise different stresses. 
 
     
     
       2. The glass article of  claim 1 , wherein the pressure-sensitive adhesive tape bonds the glass cover sheet to the frame with a bond strength of from 0.05 MPa to 5 MPa as measured at room temperature. 
     
     
       3. The glass article of  claim 1 , wherein the cured liquid adhesive bonds the glass cover sheet to the frame with a bond strength of from 0.5 MPa to 25 MPa as measured at room temperature. 
     
     
       4. The glass article according to  claim 1 , wherein the cured liquid adhesive comprises at least one of an epoxy, an acrylic, a polyurethane, polyurethane hotmelt, a silicone, or a silane modified polymer, wherein the pressure-sensitive adhesive tape is applied continuously around a perimeter of the support surface. 
     
     
       5. The glass article according to  claim 1 , further comprising a display bonded to the support surface of the frame or the second major surface using optically clear adhesive, wherein the pressure-sensitive adhesive tape encloses the optically clear adhesive such that the cured liquid adhesive does not contact the optically clear adhesive. 
     
     
       6. The glass article according to  claim 1 , wherein the first region is proximal to a perimeter of the glass cover sheet, wherein the glass cover sheet encloses the second region so that the pressure-sensitive adhesive tape prevents leakage of the cured liquid adhesive from between the glass cover sheet and the frame past the perimeter of the glass cover sheet. 
     
     
       7. The glass article according to  claim 1 , wherein the glass cover sheet comprises a strengthened glass composition. 
     
     
       8. The glass article according to  claim 1 , wherein the glass cover sheet has a thickness of from 0.4 mm to 2.0 mm. 
     
     
       9. The glass article according to  claim 1 , further comprising a surface treatment on the first major surface of the glass cover sheet. 
     
     
       10. The glass article according  claim 1 , wherein the first and second curves each comprise at least one location having a radius of curvature in a range from about 60 mm to about 10,000 mm. 
     
     
       11. The glass article according to  claim 1 , wherein the second major surface of the glass cover sheet comprises a second curve and the support surface of the frame comprises a second complementary curve that complements the second curve. 
     
     
       12. The glass article according to  claim 11 , wherein the first curve is concave and the second curve is convex. 
     
     
       13. The glass article according to  claim 1 , wherein the pressure-sensitive adhesive tape comprises continuous strips. 
     
     
       14. The glass article according to  claim 13 , wherein at least one of the continuous strips is parallel to a direction of curvature of the first curve. 
     
     
       15. The glass article according to  claim 13 , wherein at least one of the continuous strips is perpendicular to a direction of curvature of the first curve. 
     
     
       16. The glass article according to  claim 1 , wherein the pressure-sensitive adhesive tape comprises discontinuous strips. 
     
     
       17. The glass article according to  claim 1 , wherein a ratio of surface area covered by the first region to surface area covered by the second region is from 1:150 to 1:1. 
     
     
       18. The glass article according to  claim 1 , wherein the glass article experiences no delamination of the glass cover sheet from the frame after undergoing environmental durability testing according to a modified GMW3172. 
     
     
       19. A vehicle interior comprising the glass article according to  claim 1 .
